"Funny thing was that it didn't flood the entire filter. I got into a heated debate on another board about bypass filters, and how you can only hydrolock if you submerge the entire filter, but I just got some heavy spray on mine, and it just sucked a LOT of water and siezed. All cylinders were full up into the runners with water, and I had to drain it all out...I didn't really get why #1 snapped.
Even though it sucks now, something good's gonna come out of it"
yeah it'd better be heavy rain, and maybe your bumper, wheel well fender is full of holes but it's enough to make me leery.
also, with all the potential to hit a standing puddle on the freeway or whatever, u'd better be careful, or ready to install the stock airbox come rainy season.
it's a non issue UNLESS the driver is just stupid.....i have to travel roads that flood a lot....i'm normally on one side and have to get to the other....they normally get about 14-16" deep.....over my door sills......with my AEM CAI and bypass valve, i've treaded it 4 times.......all 4 times, the filter was submerged completely and the bypass valve had to open...you can tell by the sound.....nothing came of it......granted i wasn't running but 15mph or so, but hitting 1 foot of water at highway speeds will usually lead to hydroplaning, which should scare you more than hydrolock.....i've seen a ton of tests....a guy offered his pristine NSX up for that one where they submerged the filter in an aquarium of water then ran it up to 3500rpm.......the valve didn't allow the water to travel but a few inches up the pipe......and the NSX has more airflow than do any of the honda engines that will normally use it, b16, b18, h22a, etc.......stock anyway....
